• I am having trouble with my hubs not engaging properly.
There is a 3-finger prong spring that engages with the cam of our hub. One of the prongs may have broken and need to be replaced (Part number 449.04). However, most often this is caused by improper timing of the hub. Please watch our timing video for clarification.
• The locking hubs I pulled off my truck look different than MM 449S/S locking hubs.
That is correct, our hubs are manufactured to fit various models and therefore may appear different than the ones pulled off your vehicle. It is important to ensure that the 30 spline count matches.
• The hubs will not slide all the way in.
There may be some resistance preventing the hubs from sliding all the way. Reach around the wheel well and push down/up on the stub axel. This will alleviate the pressure and allow the hub to slide freely.
• I am missing bolts from the cap of my hubs.
Use a drop of blue Loctite to ensure the bolts do not back out after driving for a while. If you need replacement bolt, you can order online. Part number: 449.1412 (set of 12)
